2 Claims. 1 This invention relates to heating appliances and it hasparticular reference to gas heaters.

The principal'object of the invention is to provide a gas circulatingheater consisting of a base element on which is mounteda reticulatedhousing in superimposed and independently demountable sections, eachserving its own function with a view of utility and appearance.

Another object of the invention is to provide a burner supported in thebase at or below its top,

. whose ends and sides are spaced inwardly of the ends and sides of thebase to define an openarea intermediate the burner and base as well aswithin the confines of the burner in order to provide unrestrictedcirculation of air on each side of the radiants supported in and abovethe burner.

Another object of the invention is to provide an open frame supported onthe burner for retaining replaceable radiants in perpendicularity to theburner along its sides and ends, said frame being further adapted tosupport a vaporizing pan of substantially the same length and width ofthe frame.

With the foregoing objects as paramount, the invention has furtherreference to certain features of accomplishment which will becomeapparent as the description proceeds, taken in connection with theaccompanying drawing wherein:

Figure 1 is a perspective view of a heater embodying the principle ofthe present invention with the sections of the reticulated housingslightly displaced vertically to illustrate their separability.

Figure 2 is a plan view of the heater with the housing sections removed.

Figure 3 is a perspective view of the vaporizing pan, and 6 Figure 4 isa perspective view of the radiant frame, showing radiants thereon,certain of which are partly broken away.

Continuing with a more detailed description of the drawing, referencenumeral I denotes a substantially rectangular base, supported on legsII. The base ID has formed thereon at one end, forwardly extending,parallel arms l2, the outer ends of which are formed with bosses l3which support a service pipe M, on one end of which is a serviceconnection l5. Another boss I6 is formed on the [base l0 through whichpasses the neck I! of a burner I8, to which further reference will bemade presently. A short length of pipe l9 effects communication betweenthe service pipe l4 and burner l8 and carries a conventional valve cook20.

It will be observed, epecially in Figure 2, that the burner I8 is formedof a continuous pipe or casting whose sides and ends are parallel withbut spaced inwardly from the sides and ends of the base Ill so thatthere will be provided an open area 2| intermediate the burner and baseto permit air to circulate therethrough. Moreover, circulation islikewise afforded through the central area defined by the burner l8,hence making it possible to utilize to the maximum, the heat'given offby the radiants, which latter will be described presently. p

The burner I8 is supported in the base in by its being secured at oneend by the neck I! passing through the boss IS on the base. The oppositeend of the burner is supported by means of a protuberance 22 (Fig. 2) onthe burner, which rests upon a bracket 23, extending inwardly from theend of the base.

Supported on the burner I8 is an open frame 24, shown in detail inFigure 4 which conforms to the general shape of the burner and which isso disposed in relation to the top of the 'burner that the orifices 25in the latter will lie outside the ends and sides of the frame. Alongthe top and bottom of the frame are spaced, overhanging lips 26 whichembrace the upper and lower edges of radiants 21, which latter consistof ceramic blocks or plates which are slid into place from the ends ofthe frame 24 and assume a position perpendicular to the plane of theburner l8. Each radiant has an outer face having studs a molded thereinand has transverse perforations b therein throughout its area which is afurther aid in equal distribution of heat radiated by the radiants 21,by permitting passage of preheated air through the radiants into theopen central area of the burner for ascension through the reticulatedhousing to be described presently.

While not necessarily an essential element in the described combination,a pan 28, adapted to contain water for vaporization and humidification'purposes, is adapted to be supported on the top of frame 24'. This panis shown in detail in Figure 3.

Among the outstanding characteristics of the invention is the safetyfeature in entirely enclosing the flames, to prevent ignition ofclothing or other inflammable material. To accomplish this, a housingconsisting of sections 29 and 30 are provided, the former havingvertical walls provided with heat escape openings 3! while the uppermostsection 30 is preferably formed as shown, with inclined walls providedwith slots or other openings 32 and a reticulated top 33. The lowersection 29 of the housing may be removed, if desired, and the uppermostsection may he set directly on the base 10. Thus, the height of theheater may be reduced without interfering with its efiiciency or itsornamental appeal. It is also possible to remove the uppermost section,leaving the lower section 29 intact and cover the central area with thepan 28.

The features of convertibility described contribute much tohmaking theheater one .of general purpose with-"the paramount object to insuremaximum heat and safety.

Manifestly, the construction as shown and described is capable of somemodification and such modification as may be construedtci.;-f.allswithin the scope and meaning of the appended claims is alsoconsidered to be within the spirit and intent of the invention.

What is claimed is:

1. A heater comprising a substantiall'y're'ctam gular elevated base, aburner supported in said baseconsisting of a perforated, continuous pipelyin'g parallel- 'withthe-sides and-"ends of said base but out 'of"contigu'ity' therewith to'definean air space intermediate the said baseand *burner and within the confines" of "'thelatter, an open framesupper-tedon'said burner having spaced, overhanging 'lip-sg'r'adiantsretained ina ve'rtical plane-on said-frame at its'sides' and-endsday-said *I-ips, a reticulated housing'in' separable horizontal"Sections superimposed --on' "said" base a' "shallow water pan supportedon said frame and' -means *enteringthrough the 'erid-of 'saidbaseand'com- .the upper of said frame portions to define lips,
